o'rIs w. WARD, or vergreens-rs. 1.

To d Z ZwYwm itmay concern: q ,Be i knownthat I, OTIs W. WARma c1t1 zen of the United States, residing at Augusta, in the county of Woodrufi and State of Arkansas, have invented certain. new and useful Improvements in Back-Band Buckles,

harness and in the maintainin ;of thesame provision of a buckle which will maintain a given position and prevent slipping or displacement of the traces when the latter,

are slacked as when backing or from other causes usually resulting in the traces having free movement.

The invention also has for its object to provide a back band buckle which may be easily applied and which may be reversed to present a new supportin hook in the event of the hook engaging the trace becoming disabled from wear or any other purpose.

The invention furthermore has for its object the rovision' of a back band buckle which em odies a plurality of clamps and which are connected for simultaneous operation upon manipulating a single part.

The drawing illustrates a preferred embodiment of the invention. However, it is to be understood that in adapting the same to meet different conditions, various changes in the form, construction, and operation of the invention may be resorted to without departing from the nature of the invention as claimed hereinafter.

In the drawings Figure l is a top plan view of a back band buckle embodying the invention, the dotted lines indicating a portion of the back band.

Fig. 2 is a transverse section on the line 2-2 of Fig. 1.

Fig 3 is a detail view of a portion of one of the clamps, 7

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by like reference characters.

The buckle preferably comprises a plate 1, the same having a central portion omitted to provide an enlarged space 2. The sections or parts of the plate separated by the space 2 are connected at their ends by means of elements 3 which are relatively BACK-BAND BUCKLE. V I

mousings 6 closefthe spaces leading totthe hooks 5, thereby preventing disengagement of the traces from the hooks when engaged therewith, The keepers or .mousings 6 may beofany structural formation such as commonly provided in snap hooks.

A clamp 7 is disposed at each side of the centrally disposed space 2 and is journaled at its ends in bearings 8 at the ends of the bars or connecting elements 3. The clamps 7 are each formed of a strip which is bent into angular form between its longitudinal edges, one of the wings of the clamp being toothed, as shown in Fig. 3, so as to make positive engagement with the back band and prevent relative slipping of the parts. A An operating member 9 projects from each of the clamps 7 and is of loop form. A link 10 engages the operating members 9, and a ring or like element 11 is applied to the link 10 to be engaged when it is required to simultaneously operate both clamps to effect re- I lease thereof from the back band. When moving the clamps into active engagement with the back band pressure is applied to the link 10 whereby the clamps assume the position indicated most clearly in Fig. 2.

When the back band indicated by dotted lines in the figures of the drawing is applied to the buckle, it is trained throughthe several slots 4 and is engaged by the toothed edges of the clamps 7 This prevents any possible slipping of the buckle on the back band. The traces are engaged with the hooks .5 in a manner well understood,and

in the event of one of the hooks becoming disabled, the buckle may be reversed so as to bring the opposite hook into position to receive the trace. This applies to cases where only one hook of the back band buckle is in invention. It is to be understood that I may make such changes in the construction,

arrangement, and combination of parts, materials, dimensions, et cetera, as may prove expedient and fall withinth'es'cope of the appended claims. v

Having thus fully described my invention,

what I claim asnew and desire to secure by Letters Patent, is

1. A back band buckle-providedwith a plurality of clamps, and connecting means for operating the clamps simultaneously.

2. A back band buckle provided with a, plurality of clamps, and a link forming connecting means between the clamps whereby the same are adapted to be operated simultaneously.

3. A back band buckle, comprising a plate or frame having a centrally disposed space, and clamps arranged along the edges of such space and connecting means between the clamps'to admit of simultaneous operation thereof.

4.. A backhand buckle comprising a frame having oppositely disposed hooks and intermediate slots 'for the training therethrough of the backband, clamps for engaging the back band, and operating means for simultaneously actuating the clamps;

5. The herein described back band buckle, comprlsing a-plat'e-havmg a central portlon omitted to provide a space and provided near opposite edges with parallelslotsand having opposed hooks, clamps at opposite sides of the centrally disposed space, and

means connecting theclampsfor simulta-. neous operation.

In testimony whereof I afiix my signature in presence of two witnesses;
